Price/budget? I've got a Surge Evo (not selling) but they usually go cheap on CRC.
Surge Evo is pretty close to what I'm looking for, but only 30.9 seatpost
I was hoping to pay under $100 for a used frame, maybe under $300 for new?
If I eliminate either the seatpost, fork travel or wheel size requirement, there are a few choices in new frames, but very little I've found has all of them.
The only currently available frame with everything is the carbon ONONE 456 evo, too expensive.
Some options I've found are:
Trek 3500
Avanti Montari 26
Fireeye Flame
The first two are both old models and were never available frame-only
The Fireeye is unavailable currently (edit: just found one, but $400+)
